Anotácia

This specification covers the chemical and physical property requirements and acceptability testing procedures of expanded or exfoliated vermiculite loose fill thermal insulation. This also includes vermiculite that has been surface-treated to produce water repellency for use in installations where liquid moisture may be a factor. Vermiculite insulation is specified by two types according to treatments and five classes according to the range of particle size distribution. The insulation should conform to the specified values of bulk density, grading, water properties, thermal resistance, moisture absorption, combustibility, and surface-burning characteristics. Tests to determine the physical properties should also be in accordance with the specified test procedures.
